Choosing a profile

Profile – is a set of parameters for the result video. All the parameters influence on the size or/and quality of the video, and also on the rate of conversion. If you want to change standard parameters or add the own ones, you can do it in the "Profile Editor".

The following parameters can be called the basis ones of the Profiles:Video codec – method of video compression. Codecs are characterized according to the degree of compression video materials (the size of compressed data), the quality of video compression (the quality of the video while playing), and the rate of compression. Resolution – the size of the picture vertically and horizontally. This is the main parameter responsible for the image definition quality. But, it is necessary to take into consideration, that if the resolution is very big, you need to put big video bitrate, otherwise, the quality will decrease. Video bitrate – is also the basis parameter that is responsible for the quality of the result video. The higher the parameter, the higher the quality and size of the result file.Framerate – the number of frames per second. We advise you to leave the framerate of the initial video without changes, or in a different way, you will face the problem of having the picture bouncing. Audio codec – similarly to video codec.The frequency and number of channels.Audio bitrate – similarly to video bitrate. As it was mentioned before, the choice of a profile influences on the quality of the result video and its size. As a rule, the higher the quality, the more the size of the video. Each format and device has its own profile. Besides, all the profiles are divided into groups according to their subject, in order to make the choice easier.

The things you have to do to choose a profile:

1) choose a device you are going to create a video for;

2) choose one of the formats supported by your player;

3) choose a group of profiles;

4) choose a profile what you would like to use for video conversion

When the profile has already been chosen, in the window "Parameters" you will see the parameters of the result video (but only in that case, if at least one of the files is added in video convert
